SPECIFICATION forming part of Letters Patent No. 659,847, dated October 16, 1900.

Application led May 4, 1900. Serial Nol 15,477. (No model.)

To alt whom t may concern:

Be it known that I, MAX H. DETTE, a citi- Zen of the United States, and a resident of New York, borough of Manhattan, State of New York, have invented a new and useful Ice- Cuttiug Machine, of which the following is a specification.

My invention relates to an ice-cutting machine, with the object in view of providing 1o an expeditious and economical machine for subdividing ice into parts of varying sizes and shapes.

The means at present in common use for subdividing a cake of ice are subject to the I5 objection of excessive waste and oftentimes to uncleanliness. My present invention is intended to obviate these objections and to provide means for handling the ice in a cleanly manner and reducing the waste to a minimum. 2o A practical embodiment of myinvention is represented in the accompanying drawings, in which- Figure l represents the machine in side elevation. Fig. 2 represents the machine in front elevation. Fig. 3 is a top plan view of the table-bed, and Fig. 4 is a vertical section through the table-bed on the line 4 4E of Fig. 3.

The supporting frame conveniently consists of two pairs of supporting-legs, (denoted 3o by A A,) one pair at the front and another at the rear, the said supporting-legs being surmounted by a bed-piece B, forming a support for the table-bed and having an upwardly and forwardly extended arm B for supporting the upper saw-pulley and its guides. The table-bed is denoted as a whole by C. It is preferably of skeleton formation and is provided at its margin with a trough c for collecting water from the melting ice and with a marginal ledge c' in proximity to and inwardly from the trough c for receiving the outer edge of a marble slab D, which forms the table on which the ice is intended to rest during the cutting operation. In speaking of the table D as marble I wish it to be understood that this is at the present time the preferred substance; but other materials of a non-oxidizable nature may be employed-as, for exam ple,g1ass and aluminium. The table-bed() is provided at one side with a slot c2, opening through to the edge of the table for the purpose of admitting the saw, and the table D is provided wit-h a corresponding slot. The trough o is provided at intervals-as, for example, at c3 c4-with 55 openings in its bottom, which communicate with pipes e e', leading to a common wastepipe E at the bottom of the frame. I also locate a trough F under the slot c2 after the saw has been placed in position in order to 6o catch the drip water which may escape from the table through said pipe, and a pipe foonnects with the trough F and with the common waste-pipe E. On the table D there rests a gage G, hinged to a headpiece g, adapted to rest on the surface of the table, the said head g being attached to a stem g', which has a longitudinally-sliding movement in a supporting-bracket g2, a set-screw g3 being provided for holding the stem g' in its vari- 7o ous adjustments. The hiuging of the gage G to the headg permits the gage to rest flatly against the cake of ice, whether it be perpendicular to the table or oblique thereto, while the head g is permitted to rest on the table and determine the thickness of the piece to be cut.

At the front of the table there is an apron H, attached to swinging arms h, pivoted to hangers h', depending from the front of the 8o table-bed to permit the apron H to be swung up into position to slide cakes of ice onto or off the table or down underneath the tablebed out of the way when not needed.

The saw employed for cutting the ice is a band-saw, its position being indicated by the line I. It is mounted on pulleys z' fi, the lower pulley@- being journaled in the supporting-frame and the upper pulley t" being journaled in the overhanging arm B of the 9o supportingframe. Suitable guides K K', located, respectively, at the back and front, serve to hold the saw in position, as is usual in connection with band-saw machines. Suitable tension is imparted to the saw by the adjustment of the pulley c" in its bearings by means of the adjusting-screw t2, as is usual. The saw is operated by means of a drivepulley k, fixed on the shaft 7c of the pulley c' by means of a belt (not shown) leading to a too holding it against the gage G it is slidtoward; l

the saw and a piece or slice cut off. This .operation may be repeated until the cake has been sliced into parts as thick as; desired, and then these parts may be in turn subdivided to form pieces of the desired shape and' size. The saw itself is very thin, so that there is very little Waste by the saw-cut and' no chi ps or small bits of Waste ice areformed",

such as are commonly formed when a piece l of ice is chopped in twoor broken up by a sharp instrument or'hammer.

The table on which the cake of? ice restsmay be kept clean, the waste Waterfromthe cake of ice being conducted awayy by the trough at the margin ofthe table, 'so'thatthe machine may be used in rooms where it i's desirable to keepv the door from being soaked' with Water.

1'.. An ice-cutting machine comprising a band-saw', a table of some suitable non-oxidizable material for supporting the cake in proximity to the saw, the said table being provided With a trough at its margin for con- :veyingaway the Waste Water and a gageV for determining the position of the cake of ice *relatively to the saw, substantially as set forth.

2; An ice-cutting machine comprising a band-saw, a table of some suitable non-oxid'izable material for supporting the cake of ie; inV proximity tot the, saw, the-said table being provided with a marginal trough, a common Waste-pipe7 branch pipes leading ifrom the common Waste=pipe to the said itrough, and a gage for determining the positiony of the-cake of ice relatively to the saw, Esubstan tiallyy as set forth.

Ifntestimony that If claim the foregoing as i myfin-venti'on Ihave'signed; my name, in prese ence ofy tWo Witnesses, this 9th day' of April, 41900.
